40mm Round Fresnel Lens 28-80mm Focal Length PMMA Threaded Optical Condenser for LED DIY(40mm)

Precision-molded PMMA acrylic Fresnel lens with 92% light transmittance, delivering bright, uniform beam control for LED, stage, and flashlight applications. Versatile focal length options (28/40/50/70/80mm) allow flexible adjustment of beam angle and output, ideal for optical experiments, prototyping, and product development. Threaded edge (0.3mm pitch) simplifies integration into lens holders or housings, ensuring secure fit and stable optical alignment in DIY or production setups. Ultra-thin 2mm profile and lightweight devise minimize space and weight in compact devices, compatible with VR glasses, magnifiers, and solar condenser systems. Wide operating temperature range (-40°C to +80°C) and durable acrylic construction ensure reliable performance in indoor, outdoor, and high-heat lighting environments.
